It *should* read ext2 and ext4, but for compatibility reasons/ease of use with windows machines I guess, manufacturer settled on fat32 http://wagnerstechtalk.com/rg350tips/ >>if you are unable to see your games when inserting an external microSD, make sure the microSD card is formatted as fat32 (in windows). Formats ext2/ext3 are fine as well for other platforms. Obviously, backup any files on the microSD card before reformatting. This is a very common problem that I see in the video comments. "make sure the microSD card is formatted as fat32 (in windows). Formats ext2/ext3 are fine as well for other platforms." ... Not really sure what to make of this... "Also, macosx programs are fine as well for other platforms" ??? https://github.com/retrogamehandheld/OpenRGH/issues/15 >>RG350 1.7.9.6 ROGUE Firmware (forked from this repo) doesn't automount ext2 external sdcard to /media/sdcard #15 >>After doing so, my ext2-formatted external microsd card no longer gets automounted to /media/sdcard like it did under Firmware 1.6. And there appears to be no fstab entry for it on the read-only system volume that would cause it to automount, either -- and because the volume containing /etc/fstab is read only, I can't add one! Hm... So it *shouldn't* be a problem.... >>I think I may have found my answer in /etc/udev/rules.d/61-automount.rules. It doesn't supply a filesystem-specific options line for the ext2 filesystem; it only does so for vfat, exfat, ext3, ntfs, and ext4. This seems like a massive oversight. But it eventually turns out to be one ultimately because cards are supposed to be formatted fat32 >>The kernel don't has support to ext2 file system Jesus christ... >>The older kernels did. Why was support for it removed? Good question... >>Because is an old file system. What problem has ext3/4? But this is very easy of activate. Right >>Okay, I tried it with a fresh formatted microSD with fat32. Auto mount doesn't work either :( Have to mount it manually lol >>try to format the external microsd with the scripts format of the console, this work fine. Holy fucking cow >>not quite. if you format the card with fat32 script auto-mount doesn't work. microSD has to be formatted with the RG-350 script (exfat) then it indeed runs perfectly. To all people you can't format microSD card with Windows (fat32 or exfat)! It has to be formatted with scripts provided by RG350 1.7.9.6 ROGUE Firmware. Otherwise microSD card will not auto-mount! Omg a sea of shit lololol ... Well I'll stop there, glad I kept the stock system/install
